All National Pan-Hellenic Council, Inc. fraternities and sororities in the area are established as core/city-wide chapters which are based on the campus of Illinois State University; with one exception being Sigma Gamma Rho Sorority, Inc.. Membership in these organizations is open to IWU students as long as they meet the membership requirements and have been selected through the membership intake process.

Currently, the following NPHC, Inc. organizations are recognized at Illinois State University and therefore open for IWU students to join.

Core/Citywide chapters of Alpha Kappa Alpha Sorority, Inc. and Zeta Phi Beta Sorority, Inc. have existed but are currently not recognized by either ISU or IWU. Sigma Gamma Rho Sorority, Inc. does not establish core/city-wide chapters. 

If you would like more information about how to join one of the NPHC, Inc. fraternities or sororities or have an interest in helping to start a chapter of Sigma Gamma Rho Sorority, Inc. at IWU, please email the Office of Fraternity and Sorority Life at
